Passive partner choice through exploitation barriers

摘要: Floral features that affect the efficiency with which pollinators can harvest their resources, or profitability they obtain from them, foraging decisions of pollinators. Foraging choices pollinators, in turn, pollen flow: increases flower constancy lead to more efficient transport. It follows exploitation barriers—flower traits differentially net intake rates potential visitors—will promote resource partitioning and enhance export. In this paper we first generalise models show barriers partial even when flowers are randomly distributed space. Then develop a model study how rules removal deposition, flow. The shows partitioning, incomplete, substantially increase Finally, use computer simulations demonstrate promoting evolve. Many associated pollination syndromes have small but consistent effects on different taxonomic groups exploit flowers, be considered barriers. Even if these not strong enough strict specialisation, may little effect female component fitness limiting resource, likely selected because male fitness.
